Scientists discover how plants disarm the toxic effects of excessive sunlight

...ism is likely highly conserved across species from microbes to plants and humans - and therefore very applicable to other fields of study. For example, too much sunlight can actually be harmful to plants, because the heightened photosynthetic activity also means an increase in singlet oxygen. By modifying pl...

NASA links nanobacteria to kidney stones and other diseases

...vity on Earth, supporting earlier discoveries that microbes have radically different behavior in weightless environments. NB is also shown to possibly be an infectious risk for crew members living in close quarters. "The concept that nanobacteria are living organisms is still controversial because the resear...

LUCA technologies confirms real-time methane generation

...n to demonstrating that methane formation by these microbes can be stimulated by the introduction of nutrients or suppressed by heat sterilization or the introduction of oxygen, Luca has shown that radio-labeled CO2 (carbon dioxide) introduced to these substrate samples is converted to radio-labeled methane. ...

Family trees of ancient bacteria reveal evolutionary moves

...g some two billion years ago were becoming complex microbes that had larger cell diameters than earlier groups ?at least 2.5 microns. Blank's tree shows that several morphological traits arose independently in multiple lines, among them a sheath structure, filamentous growth, the ability to fix nitrogen, ther...
